FATE-N FFIC 5' PHILIP RICHARDS, OF WILKES-BARRE, PENNSYLVANIA.

V FlRE-GRATE.

SPECIFICATION forming part of Letters Patent No. 269,115, dated December12, 1882.

Application filed October 24, 1882. (No model.)

To all'whom it may concern Be it known that I, PHILIP RICHARDS, ofWilkes-Barre, in the county of Luzerne and State of Pennsylvania, haveinvented certain new and useful Improvements in Fire-Grates; and I dohereby declare that the following is a full, clear, and-exactdescription of the invention, which will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanyingdrawings, which form a part of this specification,and in which- Figure 1 is a top view of my improved firegrate. Fig. 2 isa longitudinal vertical sectional view of the same. Fig. 3 is a detailview of the shaking-device, andFig. 4 is a detail view of one of thegrate-bars.

Similar letters of reference indicate corresponding parts in all thefigures.

My invention has relation to fire-grates; and

it consists in theimprove d construction, combination, and arrangementof parts-thereof, as hereinafter more fully described and claimed.

In the accompanying drawings, the letter A represents the fire-place orfurnace of a steam boiler, heating-furnace, or stove, and B is theash-pit.

O is the front plate of the fire-place, provided with a door ot'anysuitable construction,

and opening to the ash-pit under the grate, provided with suitabledampers.

D indicates the grate-bars, which are laid longitudinallyin thefire-place, and reston three sets of rollers, E, F, and G. Thegrate-bars consist of two flat heads, H and I, the front one, 11, ofwhich has alongitudinal slot,J,provided with a cross-pin, K. The uppersurface of the central part of the bar consists of a series of V-shapedprojections, L, alternately higher and lower, the ends of which projecton both sides of the belly-flange M, while their points are pointingrearward. The two heads H and I and a plate, N, on the under side of thebelly-flange M rest on the three rows of rollers E, F, and G, which eachconsists of the rollers O, journaled on the shaft P,which again isjournaled in bearings Q, supported under the grate in any desiredmanner.

The shaking device is fastened to the front plate, 0, and protected fromthe fire and ashes from the fire-place by a plate, R, hingedto the videdwith a series of pitmen or books, X,

which are hinged upon them and engage the cross-pins K-of thegrate-bars--one upper and one lower hook-alternately.

It will readily be seen by the foregoing description, taken inconnection with the accompanying drawings, that by moving the bandle Vthe hooks will draw every other bar forward and push every other barback, and by repeating the motion it will shake the ashes from the fire.The ashes will fall down in the ash-pit through the spaces between theprojections; and this construction of a grate-bar will also serve tokeep it' cool and prevent it from burning out or warping, as theair-draft will continually rise between the projections and keep the'barcool. The rollers beingjournaled on a shaft, which again in its turn isjournaled in bearings supporting the three sets of rollers, will assistin their turning easy and prevent their stopping entirely, as if oneroller sticks fast to the shaft by expansion of the the shalt will turnin its bearings with the roller, or in the case of the shaft gettingfast in its bearings the rollers will turn upon it.

The whole shaking device will enable the fireman to shake his firewithout opening the doorand thus checking the draft from below.

Having thus described my invention,Iclaim and desire to secure byLetters Patent of the UnitedStates- 1. .In' a fire-grate, thecombination of the grate-bars D, mounted on rollers E, F, and G, andhaving flat heads H and I, and plate N on the belly-flange M, andprovided withV-shaped projections L, of alternate height, projectingover the sides of the belly-flange M, with the shaking device, as setforth.
